Very sad to read about another local model shop closing.
We are lucky here, not only has our local shop has just moved into larger premises but the owner's son is taking over. About half is given over to selling lego, the big 'adult' targetted set mainly, so perhaps such diversifacation is the key to local shops continuing.
Afraid it's the climate we live in. We had one here , sold mostly di- cast and a few plastic kits. He's retired now. I think shops that have an online presence and shop are the only way for them to stay in business.
